need help bad. . . nitrous isnt working

[stang94X]

i go and take my car to get a nitrous tune on the dyno today, set up for a 150 wet shot, its set up with a tps controller to start spraying at WOT, car runs great, but when it gets to WOT, and the nitrous kicks on, it whats to stall out and acts like all the fuel is being dumped in but the nitrous isnt spaying in, all the jetting is correct, both solenoids are working, and the nitrous sprays out of the soleniod, but for some reason the nitrous isnt working, so anyone have any ideas or suggestions on what could be done, thanks

did you check to make sure your WOT switch is actually engaging? When it engages are you getting the proper voltage to your nitrous solenoid? Is there anything in the line of your nitrous feed side?

yeah everything is in proper working order, its all been taken apart, checked, put back together, double checked, re-ran and checked again, several times, but for some reason it still just boggs down when it is first engaged and then its like a kick in the chest untill i let up off the pedal
